Yes, presumably in this thread we are referring to a peak level of play which the player can reproduce on a fairly regular basis in a big event, such as Davis Cup, Wimbledon.
Generally, you can assume that most players will do their utmost to reach their peak level in a big Davis Cup or Wimbledon match. One exception would be Nastase.

Nastase would rather entertain than win--ever the court jester.
